Isolation Forest Based on Minimal Spanning Tree
IEEE Access, 2022 Detecting anomalies in data sets has been one of the most studied issues in modern data analysis. Therefore, there is a plethora of applications in a very wide range of fields of science and technology.

On the probabilistic min spanning tree Problem [PDF]
, 2010 International audienceWe study a probabilistic optimization model for min spanning tree, where any vertex v i of the input-graph G(V, E) has some presence probability p i in the final instance G′ ⊂ G that will effectively be optimized.

Degree Sum Condition for the Existence of Spanning k-Trees in Star-Free Graphs
Discussiones Mathematicae Graph Theory, 2022 For an integer k ≥ 2, a k-tree T is defined as a tree with maximum degree at most k. If a k-tree T spans a graph G, then T is called a spanning k-tree of G.

On the Longest Spanning Tree with Neighborhoods [PDF]
Discrete Mathematics, Algorithms and Applications, 2018 We study a maximization problem for geometric network design. Given a set of [Formula: see text] compact neighborhoods in [Formula: see text], select a point in each neighborhood, so that the longest spanning tree on these points (as vertices) has maximum length. Here, we give an approximation algorithm with ratio [Formula: see text], which represents

Generalized minimum spanning tree games
EURO Journal on Computational Optimization, 2016 The minimum-cost spanning tree game is a special class of cooperative games defined on a graph with a set of vertices and a set of edges, where each player owns a vertex. Solutions of the game represent ways to distribute the total cost of a minimum-cost

Spanning Trees—Short or Small [PDF]
SIAM Journal on Discrete Mathematics, 1996 We study the problem of finding small trees. Classical network design problems are considered with the additional constraint that only a specified number $k$ of nodes are required to be connected in the solution. A prototypical example is the $k$MST problem in which we require a tree of minimum weight spanning at least $k$ nodes in an edge-weighted ...

MENCARI MINIMUM SPANNING TREE DENGAN KONSTREN
Jurnal Matematika UNAND, 2019 Misalkan G = (V, E) adalah graf tak berarah terhubung yang bukan tree, berarti di G terdapat cycle. Dengan cyclic interchange maka diperoleh subgraf T yang tidak memuat cycle. Subgraf T inilah yang dinamakan dengan spanning tree.

Discrete Mathematics, 1992 The paper studies spanning trees of a cactus. A cactus is a connected graph in which each block is either an edge or a circuit. A rooted graph is an ordered pair \((G,R)\), where \(G\) is a graph and \(R\) is a set of its vertices which contains exactly one vertex from each connected component of \(G\).

Linking and Cutting Spanning Trees [PDF]
Algorithms, 2018 We consider the problem of uniformly generating a spanning tree for an undirected connected graph. This process is useful for computing statistics, namely for phylogenetic trees. We describe a Markov chain for producing these trees. For cycle graphs, we prove that this approach significantly outperforms existing algorithms.
